The Arctic Ocean is the smallest of the five oceans. Its surface is almost entirely covered in ice. While this frigid body of water may seem inhospitable to life, in reality, millions of unique plants and animals thrive below the ice. The Our Five Oceans series features stunning visuals, detailed maps, educational debates, and challenging research activities. Each book explores key topics such as ocean life, ecosystems, and environmental issues, in order to help readers better understand the importance of protecting the world's oceans.
